SHIPPING-BOX.

Specification of iletters Patent. Patented Sept, 16, 1919.

Application filed J'une 16, 1916. Serial No. 103,921.

To all whom it may concern:

. Be it known that I, WILIAM SCHALK, a citizen of the United States, and resident of West Allis, in the county of Milwaukee and State of Wisconsin, have invented new and useful Improvements in Shipping-Boxes; of which the following is a description, reference being had to the accompanying drawings, which are a part of this specification.

The invention relates to shipping boxes or cases.

The invention is designed more particularly to provide a shipping box which may be made of parts readily assembled together for use as acontainer and which may be readily knocked down so as to occupy a small space when it is returned to the shipper.

One of the uses of a box of this klIlCllSi in the 1 shipping of leaf tobacco. Formerly tobacco was shipped in boxeswhich could not be readily opened for inspection and the present invention is designed to obviate thisdifliculty by providing a foldable box,

in which the ends, sides and topof the box may be thrown down and out of'the way to permit a thorough inspection ofthe tobacco. Furthermorewhile it is necessary to have a strong box for shipping purposes it is also necessary that in some classes of goods, such as tobacco, to prevent its coming in contact with any metallic reinforcement on the box and I have provided for this by so construcing the box as to provide an interior lining of wood or other suitable material forming the box sections and by binding and securing said sections by metal reinforcements on the outside of the box.

The inventionfurther designs to provide a box made up of foldable sections, each of said sections being provided with metallic reinforcements, which reinforcements are provided with detachable hinges, the sections of the box being secured together by fastening means passing throughthe reinforcements.

The invention further designs to provide a new and improvedform ofshipping box.

The invention consists in the several features hereinafter set forth and more particularly defined by claims at the conclusion hereof.

In the drawingsz shown in section;

F 2 i s an end view of the box; it F1g.3 1s a plan view of the box,the cover being raised and parts being .broken away;

' Fig. 4: is a section taken on the line e 4: ofFig.1; i

Fig. 5 is a section taken on the line 5-5 of Fig. 2; i

i Fig; 6 is a section taken on the line 6-6 ofFig.2;

Fig. 7 is a detail sectional View of one of the detachable hinges for the sections;

Fig. 8 is a view of the box in assembled unfolded condition;

Fig. 9is a view of the box similar to Fig. 8 with the sections of the box separated from each other; i

Fig. 10 is a plan 1 view of the box in knocked down condition; and

Fig. 11 is a section taken on the linell-ll of Fig. 10. i i i The box comprises a bottom 7, sides 8 hingedthereto, top 9 hinged to one of the sides, ends 10 hinged at either end ofthe bottom 7 means for reinforcing and connecting the sections 1 in assembled condition, and means for securing the sections in knocked down condition. i i

The top, bottom and sides are preferably made of solid pieces of wood or other material while the ends are made of. a plurality of PlQCBS. 11 spaced apart to provide for air spaces as in the use of the boxes in connection with tobacco it is necessarythat proper ventilation be provided.

and which are secured within transverse recesses 15 on the outer side of said sides. Detachable hinge connections are providedbetween the bottom 7 and the sides 8 and each of these consist of a detachable hinge connection between the alined reinforcing mem her-s12 and 14 on the bottom and sides of the box respectively. Each of these detachable hinges is formed as shown more particularly in'Fig. 7 by extending the members 14 outwardly from the sides 8 to form hooked ears 14 forreceiving a hinge pin 8 and the ends ofthe members 12 are bent up within recess portions 7 to formhooks 12 for et hebly engaging thepiu 8 t fo m a detachable hinge connection between the bottom and the sides ofthebox. Though the hinge connection has been described with reference to the bottom and sides of thebox, this description applies also to the detachable hinge connections between the bottom and the ends of thebox and between the top and one of the sides of,the'boxdiereinafter described. The top 9 is also provided with bars 17 secured Within transverse .recesses 18 on-theoutsidethereof and iszhingedto one of the sides 8 through the detachable hinge connections previouslydescribed. Thus it will be noted that the reinforcing members or bars 112, ltand 1'7;torm continuous bands extending around thetop, bottom and idesot the boxandare detachably secured to each other so the parts of theabox may;beseparatedandpacked ;in knockdown condition.

.The pieces 11 are connected together to form the end se'ctions 10by -a ,plurality of reinforcing bars ,1 9 which are. secured .ii1.re- .cesses .20 in said pieces extending itransversely thereof and these bars areiliingedly secured totheextensions21 through detachable hinge connections .previously described. :Theextensions 21. are. riveted to .the; bars 12 and extend at an angle thereto.

;By .reason ,of the detachable :hinges :be-

tween the sectionsithey may be .readilydisconnected .and compactly packed in knock down form, as. shown in :Fig. (11,. and secured in .this condition .by bolts :15 which pass through apertures 16in the. sections and engage in nuts 16 seated within theibottom section 7 near the outside thereof. In this Way the .parts of the -box are compactly secured to occupy small space lfor'return to theshipper. WhentheCbox is" packed the bolts 15 arepassedithroughholes 15 inthe top 9 and thence through vertical holes 110 inthe ends 10 and aresecuredLto said sides by nuts 11- seated atthelowerendsofthe holes '10' within the. ends10. bus. the bolts 1-5 serve to retain-the sectionsbothinzknockdown .and assembled positions. :It will be noted that the hinge hooks 12 onthe .bot-

tom 7 and top 9 are set into recesses *7 :in

the edges thereof thatthey will flush with saidedges, as shown more particularly in Fig. 7.

Extensions22 are riveted .to the bars :19

.and extend outwardly .fromthe ends otthe box andz have apertures 23 therein.

The end edges of the sides .8 have recesses v24 therein .to receive the extensions 22zof the bars and apertures 25 adjacent said recesses and extending lengthwiseot the sides to a position ad acent the trans- Verse bands lt. Threaded nuts 26 having lugs 27 thereon are fastened to .the' bands 14 .adjacent said apertures .25; the :lugs 27 permitting the nuts 26 to be riveted .to-the the apertures 23, 25 and into the nuts 26 which'being embedded in recesses 29 in the connect the bands 22 with the bands 4am consequently the ends 10 to the sides 8.

The top 9 has apertures 30 adjacent apertures 31 in the band 17 which apertures are .adapted tor.e ceiv.escrew bolts 82 or other suitable fastening means which pass through threaded plates-33 secured .in' the recesses 34 .inithe'edge of one oi? the side sections 8 and .rivetedto thcends of the bars 14. The screw bolts 32 thus serve to conncctthe bands 117 .and .14- togethcr and also secure the .top .to theside.

.Strips35 are. securedon-the innerside ol theibottom ;7 adjacent theends :uulserve as stops kfor theiends 10 when they are in position .and .triangular sha ped stop strips 36 on the ends 10 and sides 8 selw'edodccep the ends and sides in proper position ..when the box is assembled.

:In the useofthe boxthe sides. 8. are turned up againstithe bottom :7 andtho ends 10 are secured tp :the sides by .the bolts 28 which pass through the extensions 22 and into the nuts 26 ;in the sides 8. :Tlle box .is vthen packed and the .top .iSftllQll seeuredito the oppositelside section 8tby the bolts 32. If

it .isdesired-to inspect the contents of the :box thezbolts 28 are lemovedand.the ends dropped downand thebolts 32 removed and .the top and sides, dropped downdeaving the 1 contents. of i the: box resting upon the 1 bottom 7 .open to inspection.

Atter .the shipment has been made the consignee detaches .t he hinged sections as previously described secures them together :in stacked relation and-inthis condition the .box :is returned .to the shipper.

iFrom-theforegoing description it will be .noted that the .interior of the boxis .vvholly of .wood or. other. suitable material and that the metal reinforcement .also serves :to do tachahly secure :the sections of the box together so that thebox may bereadily inspected andalso returned to the shipper in YkllOGkdOWll condition.

What I claim. asmyinvention is:
